Perma “R” Brace SIB is a lightweight, 4-in-1 structural sheathing solution that provides four layers of enforced protection against water, moisture vapor, mold, and more. All the benefits of our Perma “R” Brace with the added value of our stable, R5 per nominal inch GPS (Graphite Polystyrene) rigid foam. 

Perma “R” Brace incorporates an air and moisture barrier on both sides of our light-weight structural sheathing for a cost-saving replacement for OSB. Saving on labor and material costs, our sheathing line offers a better alternative to OSB and other expensive, heavier panel system competitors. 

The ZIP Sheathing System is a one-of-a-kind structural roof and wall system with a built-in energy-efficient barrier that keeps moisture out and reduces air leakage, while still allowing panels to properly dry.

Any long length wall sheathing can reduce the number of horizontal joints and the need for blocking, but these walls still rely on traditional housewrap to complete the job. Only ZIP System® long length sheathing combines the benefits of a longer panel with the ability to completely eliminate housewrap. Can your long length sheathing do that?

For installation convenience and exceptional, long-term performance, the all-in-one ZIP System® R-Sheathing panel provides a new approach to sealing and insulating the building envelope. One panel delivers thermal, air and moisture resistance, while providing excellent strength and durability.
